Those nightmares people tend to have related to their occupations. Often it tends to be a reoccurring nightmare and a supervisor is a prominant figure in the dream usually.

Wally recently started a new job as a master control operator at the local television station. He is the person responsible for making sure the television shows air perfectly. He is completely stressed out due to the fact that the job is hyper-technical and his work is being watched by thousands of viewers at any given time.
Now he's having jobmares. In these dreams he is constantly off-air and his boss either stands quietly behind him or screams in his face... and his entire shift becomes one major shitstorm and Wally's name becomes the source of constant putdowns around work. Then he wakes up.
He airs Headline News every shift at his job. The jobmares are ruining his sleep almost nightly. Last night he fell asleep at home with the tv on, then headline news came on and Wally snapped awake... thinking he missed his commercial break and ended up shitting the bed.
